A legal dispute involving President Donald Trump's authority to remove heads of independent federal agencies has reached the U.S. Supreme Court. Two officials who were fired by Trump have urged the justices to uphold the independence of these agencies and reject the president's attempt to fire them without cause. The case challenges a 90-year-old Supreme Court precedent that has historically protected independent agency leaders from removal except for cause. Trump's recent firing spree of independent agency heads is being scrutinized under this precedent, with the court expected to consider whether to expand the president's removal powers, potentially overruling the longstanding legal framework that limits such firings.
